“Happy Earth Day everyone! What a beautiful world we live in,” he wrote. “Let’s all embrace our shared responsibility to each other to take care of our one and only planet Earth.”

Justin Trudeau also expressed the importance of protecting our planet, writing alongside a photo of himself walking through a forest: “We only have one planet. Our kids are counting on us to keep it clean and healthy.”

The Duke and Duchess of Sussex shared their support for the planet on Instagram, where they shared photos taken by Prince Harry, including an African Rhino, Botswana’s Okavango Delta, lions, and humpback and orca whales.

“Every one of us can make a difference, not just today but everyday,” the couple wrote.
